{"title":"Why?","authors":"Ivan Darby","doi":"10.1111/adj.70045","DOIUrl":"10.1111/adj.70045","url":null,"abstract":"&lt;p&gt;A couple of years ago the Australian Dental Journal published a paper looking at the dearth of research funding for dentistry, which sadly hasn't changed. For this editorial I want to look at the ‘dearth’ of academic staff in dental schools. Academic staff are essential for teaching students to practice as dental professionals.&lt;/p&gt;&lt;p&gt;It is a worldwide phenomenon and not just confined to Australia and likely New Zealand by extrapolation. Sadly, it's an issue that has been persisting for a number of years and looks not to be getting any better. So the question is why?&lt;/p&gt;&lt;p&gt;Using Dr. Google and AI (shortage of Australian dental academics), the following came up and I repeat them as they nicely sum up what the literature reports and anecdotally from talking to colleagues.&lt;/p&gt;&lt;p&gt;Interestingly, the first point that came up was income. Academic salaries lag ‘far’ behind what can be earned in private practice, especially for dentists and dental specialists. In the UK, this disparity is recognised by a separate clinical lecture pay scale, but even though there is a clinical loading in some Australian universities, this does not compensate much. Some universities allow intra-mural or part-time practice, but usually at their discretion, which helps but does not equate to private practice.&lt;/p&gt;&lt;p&gt;Lack of clear and established career pathways was second then workload followed by lack of support. Also highlighted was an ageing workforce. Many academics ‘cite poor working conditions, lack of mentorship and limited research opportunities’. I would add to this the cost of training. With a huge debt why would someone go into a profession with relatively poor salaries compared to private practice?&lt;/p&gt;&lt;p&gt;Prof Lalloo published a very interesting paper last year (https://doi.org/10.1111/eje.13146) looking at exactly this topic. He surveyed a large number of dental academics around Australia. The responses indicated a workforce between 30 and 50 years, but worryingly almost 20% were over 60. So they are likely to retire soon. Over 50% were born overseas and 40% received a non-Australian qualification, which may or may not be recognised. Comments raised were around balancing work and family, teaching workload versus time for research, and lack of mentorship. What is interesting is the apparent lack of Australians who are interested in academic careers. What is happening that puts them off? Is it all of the above or related in some way to the experience they have as students? It's clear that Australia can't and shouldn't rely on overseas trained dentists as it is not a sustainable model.&lt;/p&gt;&lt;p&gt;The Australian Dental Council (ADC) released its ‘Dental Academic Workforce Statement’ in 2022 noting the lack of academic staff and sustainability issues (my paraphrasing). The solutions were common sense and reflected the points above.&lt;/p&gt;&lt;p&gt;So, we know the problem, what the shortage may lead to and the solutions, but there seems to be nothing in between and a lack of successf","PeriodicalId":8593,"journal":{"name":"Australian dental journal","volume":"71 1","pages":"3-4"},"PeriodicalIF":2.4,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adj.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146225268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growing demand for efficient, predictable, aesthetic, and outcome-driven prosthodontic treatments has led to increasing adoption of digital workflows. This integration has transformed each step of prosthodontic treatment, resulting in three digital workflows: laboratory, clinical, and combined clinical-laboratory workflows. Although most prosthodontic treatments can now be executed digitally, a universally applicable digital workflow is yet to be established.

This progression has overcome many limitations of 2D imaging, including superimposition and distortion, enabling more accurate visualisation of complex anatomical structures. Despite CBCT's higher radiation dose compared to 2D imaging, ongoing advances in low-dose protocols and artefact reduction algorithms have expanded its clinical applications. Integration with digital tools such as intraoral scanners and CAD/CAM systems has further enhanced its utility in guided implant surgery, orthodontic appliance design, and forensic dentistry. Emerging artificial intelligence technologies promise to improve image analysis, diagnostic accuracy, and workflow efficiency. Emphasising radiation safety and careful imaging selection remains essential. Additionally, magnetic resonance imaging and ultrasound are gaining attention as non-ionising imaging alternatives, offering valuable soft tissue assessment complementary to CBCT's strengths in hard tissue evaluation.
